ments closed by doors l3 and I4. Referring now to Fig. 3, a partition I5 is shown separating the drawers II and I2, while a further partition I6 is shown supporting the drawer l2.

A sliding locking bar I? is supported for sliding movement by brackets I8 and I9 and is spring pressed to the left by a spring 28, being controlled against movement tothe left by a cylinder lock 2| having a bolt 22 and operating in a manner set forth in my patent supra. The bolt 22 prevents movement of the bar and cylinder look, as is shown also in my patent supra. When the key plug of the cylinder lock is rotated as is well known in this art, it retracts the bolt 22 in the usual way, and when the bolt 22 is thus retracted, the locking bar I! moves to the left from its locked position in Fig. 3 to a release position under the influence of spring 20. In this position, the end of the cylinder lock 2| will of course protrude somewhat relatively to the end furniture panel.

ihe locking bar ll is integrally secured as by welding or other means to a vertical bar 23, and is braced thereto as by welding or otherwise by an angular bar 2 A bracket 25 secured to the partition iii, a further bracket 26 secured to the supporting portion l6, and an upper bracket 2?, guide the vertical bar 23 and therefore guide the bar I'll for horizontal sliding movement.

Secured to the vertical bar 23 is a locking lug 28 and a further locking lug 29 which cooperate with brackets to and Si secured respectively to the drawers H and F2 for locking those drawers, as is well set forth in my patent supra. In so far as I have now described my invention, it embodies only those features of the construction which are incorporated in my said patent.

I shall now describe the means for locking the doors l3 and i4. Secured to partition 32 defining the compartment 33' controlled by the door M are a pair of bearing members 34, best illustrated in Figs. 5 and 11. A locking rod 35 is mounted for rotation in these bearing members 3d and is 'swedged out at 36 and 31 to prevent endwise movement of the said rod relatively to said bearing members. At its outer end, the rod 35 carries a locking lug 38 which is adapted to enter a slot 39 in the door M for locking the door, as is quite well illustrated in Fig. 5. Naturally, the length of the rod 35 may readily be changed to adapt it to furniture of varying depth.

The inner end of the rod 35 is equipped with a bell crank'portion 40 which cooperates with the slot-M of a cam plate 42. This cam plate 42 is secured, as is best shown in Figs. 3 and 12, to the locking rod l'l, it being understood that the securing means illustrated in Fig. 12 are only one of many types. This type of securing means is selected because it is adjustable, the cam plate 42 being secured to the bar ll in any one of many positions, limited only by the length of the bar ll. Similarly, the slot fill may be made quite long and may, as a matter of fact, extend for the -full length of the cam plate 42, so as to cooperate readily with the bell crank portion of the rod 35, regardless of'where the rod 35 is mounted with respect to the vertical dimensions of the bufiet IE3.

Because of this construction, it is readily seen that my cam plate =12 is readily capable of oper ating a locking rod 35, regardless of where that looking rod may be placed relatively to the horizontal or vertical dimensions of my piece of furniture. I

Fig. 6 illustrates what happens When the cam plate 42 moves from the locked position of Fig. 6

- to the release position of Fig. 9; that is, when the locking bar moves from its locking position of Fig. 3 to the left to a release position. Such movement will naturally cause the rod 35 to rotate, bringing the locking lug 38 from the position of Fig. 6 to the position of Fig. 9 and out of the slot 39 in the door, It, as is well illustrated.

Figs. '7, 8 and are similar to Figs. 5, 6 and 9, except that they illustratethe action with regard to the unlocking and locking of the door l3. It is thought unnecessary to describe in detail at this time the action of the parts with regard to the door 43. For convenience, in those figures the same reference numerals are used as for like parts in Figs. 5, 6 and 9.

I believe that the advantages and merits of my construction will now be readily appreciated by those skilled in the art. I should like to have it understood, however, that I feel myself entitled to rather broad claims covering the contribution I have made to the art, in order that I may be protected against the utilization by others of the basic principles of my invention while incorporating the said principles in a specific form not shown by me.

I now claim:

1. An article of furniture having a series of sliding drawers and a series of compartments closed by swinging front doors, a horizontally sliding locking member secured in juxtaposed relation to the backs of the drawers, means whereby said locking member locks said drawers when said locking member slides horizontally, a rod for locking each of said front doors, said rods extending from substantially the plane of the said sliding locking member to said front doors, means supporting said rods in position, cam plates secured in adjustable horizontal relation to said sliding locking member, and portions on said cam plates cooperable with end portions of said rods for moving the rods relatively to said supporting means and into door locking position.

2. An article of furniture having a series of sliding drawers and a series of compartments closed by swinging front doors, a horizontally sliding locking bar secured in juxtaposed relation to the backs of the drawers, means whereby said bar locks said drawers when said bar slides horizontally into locking position, a rotating rod extending from substantially the plane of said bar to each of said front doors and having portions for locking said doors when rotated into locking position, the ends of said rods terminating in the plane of said bar being in the form of cranks, vertical cam plates secured to said bar in positions corresponding to those occupied by the crank ends of said rods, and vertical slots in said cam plates into which said crank ends enter whereby horizontal sliding of said bar and cam plates rotates said rods into and out of locking position. a

3. An article of furniture having a series of sliding drawers and a series of compartments closed by swinging front doors, a sliding locking member secured in juxtaposed relation to the backs of the drawers, means whereby said locking member locks said drawers when said locking member slides horizontally, additional locking means extending from said sliding locking member to the front doors of said compartments, and means whereby said additional locking means are actuated to lock said doors by the sliding of said sliding locking member.
